The two-horizon growth portfolio card
Separate current-engine execution from future-option search, then give each mode an appropriate learning test.
| Synthetic portfolio view | Exploration | Exploitation |
|---|---|---|
| Illustrative share of attention | 35% | 65% |
| Primary question | What could become valuable? | What can become reliable now? |
| Typical activity | Search, variation, experiment | Refine, choose, produce, implement |
| Evidence of progress | Learning that changes a next decision | Repeatable performance under a declared boundary |
| Main failure signal | Novelty without selection or transfer | Current efficiency with a shrinking option set |

Each line is a claim from the register this journal publishes against, resolved from the register at build time.
- A Exploration involves search, variation, experimentation, and innovation, while exploitation involves refinement, choice, production, and implementation. March. (1991) ·
MAR91-C1 - A Organizational learning faces a tension because systems that favor exploitation can improve current returns while reducing long-run adaptability, whereas excessive exploration can undermine competence and returns. March. (1991) ·
MAR91-C2 - A The balance between exploration and exploitation is shaped by feedback, socialization, competition, and the time horizon over which learning is evaluated. March. (1991) ·
MAR91-C3 - A The definition, verbatim: ambidexterity is "the ability of an organization to both explore and exploit" O'Reilly & Tushman. (2013) ·
OT13-C1 - A The two regimes are named in the same sentence: mature markets "where efficiency control and incremental improvement are prized" against new ones "where flexibility autonomy and experimentation are needed" O'Reilly & Tushman. (2013) ·
OT13-C2 - A The dilemma in the author's words: "how to exploit existing product innovation competencies competence exploitation while avoiding their dysfunctional rigidity effects by renewing and replacing them with entirely new competencies competence exploration" Atuahene-Gima. (2005) ·
ATU05-C1 - A The proposed resolution: "customer and competitor orientations ensure simultaneous investments in exploiting existing product innovation competencies and exploring new ones" Atuahene-Gima. (2005) ·
ATU05-C2 - A And the outcome side, including the moderator: "competence exploitation and exploration have opposing relationships with incremental and radical innovation performance", while "the relationship between competence exploration and radical innovation performance is positively moderated by interfunctional coordination" Atuahene-Gima. (2005) ·
